Description
PT6959 is an LED Controller driven on a 1/4 to 1/7 duty factor. Fourteen to eleven segment output lines, 4 to 7
grid output lines, one display memory, control circuit are all incorporated into a single chip to build a highly
reliable peripheral device for a single chip microcomputer. Serial data is fed to PT6959 via a three-line serial
interface. Housed in a 28-pin SO Package, PT6959’s pin assignments and application circuit are optimized for
easy PCB Layout and cost saving advantages.
FEATURES
• CMOS technology
• Low power consumption
• 8-step dimming circuitry
• Serial interface for clock, data input, strobe pins
• Available in 28-pin, SO package
